Left-Handers’ Day
International Left-Handers’ Day is August the thirteenth. The International Left-Handers Day, Web site says the Left-Handers Club started the holiday in 1992. It wanted left-handers around the world to celebrate. And it wanted to bring attention to the everyday problems of people who use their left hands.
One of these problems is difficulty using equipment and tools, like scissors. In general, most tools and equipment are made for people who are right-handed. The Left-Handers Club tries to educate designers and producers to consider the safety of left-handed people when producing their products.
Another problem is that many people have considered it bad to be left-handed. Some teachers and parents have tried to force children who used their left hands to use their right ones instead.
Scientists do not really know why some people are left-handed. They have believed the reason is genetic.They say the gene（基因） increases the chance of being left-handed. It appears to play an important part in deciding which part of the brain controls different activities. In right-handed people, the left side of the brain usually controls speech and language. The right side controls feelings. However, the opposite is often true in left-handed people.
Scientists believe the gene is responsible for this. The gene showed a link with left-handedness in nine to twelve percent of the population.
About ten percent of people around the world are left-handed.
